The raw mixture is prepared smesheniem a ball mill and calcined in a rotary kiln at a maximum temperature of about 1450 o C the resulting clinker with the addition of gypsum to about 5 wt ground to a specific surface area of about 350 m 2 /kg The composition of the raw mix and the properties of the cement are shown as table 1 and 2.
A raw mill is the equipment used to grind raw materials into rawmix during the manufacture of cement Rawmix is then fed to a cement kiln which transforms it into clinker which is then ground to make cement in the cement mill The raw milling stage of the process effectively defines the chemistry and therefore physical properties of the finished
At raw mill crushed limestone clays and feldspar of desired chemical compositions are fed through electronic weigh feeders Clinkerisation is the heart of cement manufacturing process where the raw material is fed to pre heater at controlled rate through electronic weigh feeder.
Calculation of compound composition of cement Bogue formulations are used to determine the compound compositions of PC containing no secondary materials and having A/F ≥ These compound compositions may be calculated from the oxide analysis as follows C S A F and S denote the of CaO SiO 2 Al 2 O 3 Fe 2 O 3 and SO 3
